Vostro A840 choppy sound after upgrading to windows 7

Hi,

I recently bought a vostro a840..did a clean installation of windows 7. Since the separate drivers for windows 7 arnt out yet..i installed the Vista drivers that came with the cd. Everythings working fine other than the sound from the laptop that is really choppy with a lot of breaks. Tried everything in vain including the WIFI and dell diagnostics. In no state of playing music or even watching a movie. The sounds ok when using a headphone...its the internal speakers.

Hey thans for replying jim. By the wifi i meant that in some forums i came across users who stated their wifi devices were interfering with their sound from the laptop. so what i tried was changing the band..(a.b.g)..even the drivers..but to no avail. Even tried different drivers for the sound card (conexant smart audio 221) Done everything including the use of the generic windows 7 sound driver...no change in the choppy sound..

Hi saquib45

I might have been the one who suggested you to disable the
wireless adapter .But as far as I remember you complained about noise
in your headphones AND the speakers.

The fact that the sound from
your headphones is fine and the noise occurs only through your speakers
means that something might be wrong either with the amplifier or the
speakers themselves as "Jimco" rightly pointed out.Usually the speakers
share the same amplifier output with the headphones(when you plug in
the headphone a mechanical switch disconnects the speakers) - so it's
highly likely the speaker system.I once had a problem with integrated
speakers on an external TFT-panel.When I opened the panel to check the
amplifier I was surprised that the output signal was absolutely fine.So I
removed the speakers and when I did so I found a loose screw(!)
caught between the membrane of the speaker and the panel....the bouncing
srew caused the crackling noise....you see there are a lot of options that
can create problems.

Use the speaker balance option in your software (if available ) to find out if only one speaker causes the problem.
